Passive switching mixer volatge conversion gain calculation and its varition with frequency

Hi All,

I am trying to do a passive switching mixer volatge conversion gain simulation. The circuit consists of a MOS transistor driving a resistive load. The gate of MOS is driven by a rail to rail square pulse.

I tried the steps given in the Application note "Mixer design using Spectre RF " , but it didn't give meaningful results.

Is there any application note that deals specifically with passive switching mixers with LO being driven by a rai to rail signal or a similar situation ?

Best Regards

Vishal

I agree with Andrew - this sort of question is best handled by Customer Support - they can dedicate more time and energy to answer questions.
There is an existing Solution on Cadence Online Support that you may want to look at:

Also, if you are using BSIM transistor models in your circuit, see this paper:
